Honeywell 900H02-0202 ControlEdge HC900 24VDC 16-Channel Sinking Digital Output Module

Product Overview

The Honeywell 900H02-0202 is a 16-channel 24VDC sinking digital output module for the Honeywell ControlEdge HC900 PLC system. This module provides high-side switching (current sinking) outputs for controlling DC-powered field devices, with overcurrent protection organized in groups for reliable industrial operation.

Key Specifications

• Channels: 16 digital outputs
• Output Voltage: 6.5–32 VDC
• Output Type: Sinking (high-side switching)
• Current per Channel: 1 A continuous
• Maximum Module Current: 8 A total
• Power Consumption: 340 mA @ 5VDC (from rack backplane)
• Response Time: 6 ms ON / 6 ms OFF
• Channel Grouping: 2 groups of 8 channels
• Overcurrent Protection: Per group (8 channels per group)
• Operating Temperature: 0°C to 60°C (32°F to 140°F)
• Status Indicators: Green LED per channel, scan/fault LEDs

Compatibility

The 900H02-0202 is compatible with:

• Racks: All HC900 4-slot, 8-slot, and 12-slot racks
• Processor Modules: All 900CP1 series CPMs
• Terminal Blocks: Compatible with barrier and Euro-style terminal blocks

Installation Guide

1. Power down: De-energize the HC900 rack before module installation.
2. Insert module: Install the 900H02-0202 into any available I/O slot.
3. Secure module: Lock the retention lever to ensure proper backplane connection.
4. Wire outputs: Connect field device positive (+) to the output terminal and negative (-) to the COM terminal for each group.
5. Apply power: Energize the rack and verify green LEDs illuminate when outputs are commanded ON.
6. Test overcurrent: Verify that a short circuit on any channel disables only its group of 8 channels.

FAQ

Q: What happens during an overcurrent event?

A: If any channel in a group of 8 experiences a short circuit, the entire group is switched off. Power cycling is not required to reset the module.

Q: Can I mix sourcing and sinking outputs in the same rack?

A: Yes. The HC900 rack supports both 900H02-0202 (sinking) and 900H32-0302 (sourcing) modules simultaneously.

Q: What is the maximum inrush current?

A: The module supports 2A inrush current for 100 ms per channel.

Selection Tips

• Use the 900H02-0202 for DC sinking applications where field devices share a common positive supply.
• For sourcing applications (current sourcing to loads), select the 900H32-0302 32-channel module.
• Ensure total module current does not exceed 8A. Distribute high-current loads across multiple modules if necessary.
• Wire each group of 8 channels to a separate COM terminal for optimal fault isolation.
